Rolls-Royce is expanding its mtu gas engine portfolio for power generation and cogeneration to run on hydrogen as a fuel and thus enable a climate-neutral energy supply. Gensets powered by mtu Series 500 and Series 4000 gas engines can currently be operated with a gas blending of 10%. Beginning in 2022, operation with a hydrogen content of 25% will be possible.

“After intensive tests on test benches and pilot installations at customers in 2022, Rolls-Royce will continuously market new mtu Series 500 and Series 4000 gas engines beginning in 2023 for use with up to 100% hydrogen, and on a design to order basis conversion kits to allow already installed gas engines in the field to run on 100% hydrogen,” said Perry Kuiper, president of sustainable power solutions at Rolls-Royce Power Systems.

Fuel cells powered by 100% green hydrogen can also play an important role in future energy supply in combination with renewable energies. At its Friedrichshafen headquarters, Rolls-Royce’s Power Systems division has installed a 250 kW fuel cell demonstrator, which will be used to test and present future carbon dioxide-free energy systems to customers. The entire hydrogen ecosystem, including the infrastructure for supply, conversion, test benches and future production, is also being mapped in the company's own plants, thus building up expertise.

With its Net Zero at Power Systems climate protection program, Rolls-Royce's Power Systems division has set itself the target of saving 35% of greenhouse gas emissions by 2030 compared to 2019 using new technologies. This near-term target plays an important role in the Rolls-Royce Group's ambition to achieve carbon neutrality by 2050 at the latest. In addition to new technologies, a key element in achieving these targets is the certification of key mtu engine products to run on sustainable EN 15940 fuels such as e-diesel and second-generation biofuels as early as 2023.
